install_mistnet_from_file: Install 'MistNet' libraries from files

Description

Installs 'LibTorch' and 'MistNet' dependencies from files.

Usage

install_mistnet_from_file(
  version = "1.12.1",
  libtorch,
  libmistnet,
  mistnet_model = NULL,
  ...
)

Value

a list with character urls

Arguments

version: The 'LibTorch' version to install.
libtorch: The installation archive file to use for 'LibTorch'. Shall be a "file://" URL scheme.
libmistnet: The installation archive file to use for 'MistNet'. Shall be a "file://" URL scheme.
mistnet_model: The installation archive file to use for the model. Shall be a "file://" URL scheme. Is optional!
...: other parameters to be passed to install_torch()

Details

When install_mistnet() initiated download is not possible, but installation archive files are present on local filesystem, install_mistnet_from_file() can be used as a workaround to installation issues. "libtorch" is the archive containing all 'LibTorch' modules, and "libmistnet" is the 'C' interface to 'LibTorch' that is used for the 'R' package. Both are highly platform dependent, and should be checked through get_install_urls()

> get_install_urls()
$libtorch
[1] "https://download.pytorch.org/libtorch/cpu/libtorch-cxx11-abi-shared-with-deps-1.10.2%2Bcpu.zip"
$libmistnet
[1] "https://s3.amazonaws.com/vol2bird-builds/vol2birdr/refs/heads/main/latest/Linux-cpu.zip"
$mistnet_model
[1] "http://mistnet.s3.amazonaws.com/mistnet_nexrad.pt"

In a terminal, download above zip-files.

%> mkdir /tmp/myfiles
%> cd /tmp/myfiles
%> wget https://download.pytorch.org/libtorch/cpu/libtorch-cxx11-abi-shared-with-deps-1.10.2%2Bcpu.zip
%> wget https://s3.amazonaws.com/vol2bird-builds/vol2birdr/refs/heads/main/latest/Linux-cpu.zip
%> wget http://mistnet.s3.amazonaws.com/mistnet_nexrad.pt

Then in R, type:

> install_mistnet_from_file(libtorch="file:///tmp/myfiles/libtorch-cxx11-abi-shared-with-deps-1.10.2+cpu.zip",
     libmistnet="file:///tmp/myfiles/Linux-cpu.zip",
     mistnet_model="file:///tmp/myfiles/mistnet_nexrad.pt")

Examples

Run this code

# get paths to files to be downloaded
get_install_urls()
# download the files to a directory on disk, e.g. to /tmp/myfile,
# then install with:
if (FALSE) {
install_mistnet_from_file(
     libtorch="file:///tmp/myfiles/libtorch-cxx11-abi-shared-with-deps-1.10.2+cpu.zip",
     libmistnet="file:///tmp/myfiles/Linux-cpu.zip",
     mistnet_model="file:///tmp/myfiles/mistnet_nexrad.pt")
}
